Specification forming part of Letters Patent No. 56,128, dated July 3, 1866.

To all whom it -znay concern:

Be itknown thatI, OHAUNGEY L. SWALKER, ofthe city of Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Mosquito-Bars; and I do hereby declare the following to be a full and exact description of the same, reference being herein had to the drawings accompany ing this specification, and which make part of the same.

The nature of my invention consists in an adjustable frame, iitting window and door frames of differing widths, and in the manner of attaching thereto the netting, of either iron wire or cloth. Y

In the accompanying drawings, Figure l is the frame and 'bar complete. Fig. 2 shows adjustable end piece with springs; Fig. 3, the other end piece without springs and with set' screws; Fig. 4, the top and bottom extensionbar.

The same letters refer to the same parts in each figure.

The wholeframeis constructed with two thicknesses ofstu', a b, screwed together, the netting being secured and held between the pieces. The top and bottom rails, A, have their two parts held tpgether by the set-screws c, and a slot, d, in the frontpart allows of extensions and contractions in width of the frame, a tongue and groove at one end, on either side, guiding and keeping them in line. (See e.) In the end rails, B, a groove, f, is made, into which the strips g tit, being held and guided by the rods h, that are fast to the strips at one end and enter holes bored in the upper and lower rails, moving freely therein. A strip, fi, is fastened to the window-frame, to which the outer edge ofthe strips g are t-tedto slide thereon.

Upon the rods lt, on one side, springs n are put, and on thev rods on the other side the setscrews o press and keep the piece g stationary, to provide for irregularities of width in the window-frames and to retain the bar in the place it is put.

The netting or wire-cloth is doubled in the middle when putin the frames, to admit eXtension and contractionot1 the same.

I claiml l. The frame adjustable by the slots a and screws e, in combination with the wire-cloth upon both parts of the frame, as herein specified. f

2. The strips g, constructed and combined with the frame in the manner and for the purpose set forth.
